Research On Automatic Generation Of WebApp Technology Based On MDA

The fast development of the Internet,it is also inseparable from the development of the software industry.Of the change of the mode of access to the Internet.In many situation,people do not want to download some applications.They are more willing to use the browser directly,so that WebApp has been appeared.WebApp does not need to download and install,is a kind of application which is survival in the browser.Though light applications like WebApp are easy to use,but In the software development life cycle perhaps because of a variety of reasons,the WebApp need to be changed or improved.It is the reason to constantly modify a lot of places,which led to the software development speed can not keep up with the changes in user demand,the development of a large extension of the time,the de,velopment of the cost increase and maintenance update difficulties.And the development of lightweight software should focus on the realization of specific functions,user usability and the design of user experience.In order to solve this problem,One plausible way is using MDA(Model Driven Architecture)development ideas to developing WebApp.Therefore,this paper mainly describes:1?The significance of this study and the introduction of related technologies used in this paper;2?The existing WebApp development framework MDWAF(Model Driven WebApp Development Framework)and it's description and functional explanation;The mainly description of MDWAF(Model Driven WebApp Development Framework)and function explanation;3?Put forward the improved MY_MDWAF framework of the MDWAF framework,add the lack of conversion in MDWAF of computation independent model(CIM)to the platform independent model(PIM);4?The definition and design of the conversion rules of the PIM graphics model to the PIM text model under the MY MDWAF;5?The PIM to the platform specific model(PSM)conversion process description and the generation of specific code under the MY MDWAF;6?Through a simple example to illustrate the feasibility of the WebApp development process in the MY MDWAF.
